The following relates to wireless communications, including downlink control channel monitoring occasion configuration for on-demand system information.

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE).

Details of one or more implementations of the subject matter described in this disclosure are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages will become apparent from the description, the drawings, and the claims. Note that the relative dimensions of the following figures may not be drawn to scale.

A wireless communications system may implement techniques for network energy savings, such as by implementing on-demand system information or on-demand system information blocks (SIBs). For some implementations of on-demand system information, a network entity may transmit system information, such as a system information block 1 (SIB1), in response to an uplink wake up signal (WUS) received from a user equipment (UE). The network entity may transmit a random access response (RAR) message based on receiving the WUS, and the RAR message may configure the UE to monitor for the on-demand SIB1. In some cases, the UE may begin to monitor a downlink control channel window after a time offset from a reference time point. The reference time point may be, for example, receipt of the RAR message. The network entity may transmit multiple RAR messages within an RAR window. Based on time differences between a first RAR message (e.g., transmitted earlier in the RAR window) and a second RAR message (e.g., transmitted later in the RAR window), the downlink control channel window at the network entity may be larger than the downlink control channel window at a UE. The larger downlink control channel window at the network entity may correspond to higher network energy consumption, as the network entity may be in a higher power state for longer.

A wireless communications system described herein supports techniques for configuring a start time and a duration of a physical downlink control channel (PDCCH) monitoring window for on-demand system information, such as on-demand SIB1. By configuring the start time and the duration of the PDCCH monitoring window, a network-side PDCCH window may be aligned with a UE-side PDCCH window. In some examples, a WUS configuration or the RAR message may indicate the start time or the duration, or both, of the PDCCH window. Additionally, or alternatively, the start time and the duration of the PDCCH window may be statically configured for the wireless communications system. In some examples, the start time may correspond to an offset from a reference time, such as an RAR window. The reference time may be indicated by the WUS configuration, the RAR message, or be statically configured for the wireless communications system. In some examples, different RAR messages, such as for different UEs, transmitted in a same RAR window may indicate different or common parameter values.

In some examples, the wireless communications system may support slot aggregation for on-demand system information, such as on-demand SIB1. The RAR message or the WUS configuration may indicate a slot aggregation parameter for the on-demand system information. A network entity may transmit on-demand SIB in consecutive slots according to the slot aggregation parameter. In some examples, the slot aggregation techniques may include aspects of indicating a start time and duration of a PDCCH monitoring window. For example, if the network entity receives requests for on-demand SIB from different UEs based on different synchronization signal blocks (SSBs), the network entity may indicate different start times and durations for respective downlink control channel windows to transmit the on-demand SIBs to the different UEs.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to PDCCH window alignment configurations, slot aggregation configurations, process flows, apparatus diagrams, system diagrams, and flowcharts that relate to downlink control channel monitoring occasion configuration for on-demand system information.

In some examples, network entitiesmay communicate with one another via backhaul communication link(s)(e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities) or indirectly (e.g., via the core network). In some examples, network entitiesmay communicate with one another via a midhaul communication link(e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link(e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication link(s), midhaul communication links, or fronthaul communication linksmay be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link), among other examples or various combinations thereof. A UEmay communicate with the core networkvia a communication link.

105 140 105 140 105 140 One or more of the network entitiesor network equipment described herein may include or may be referred to as a base station(e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, a network entity(e.g., a base station) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entityor a single RAN node, such as a base station).

105 105 105 160 165 170 175 180 170 105 105 105 In some examples, a network entitymay be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities), such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, a network entitymay include one or more of a central unit (CU), such as a CU, a distributed unit (DU), such as a DU, a radio unit (RU), such as an RU, a RAN Intelligent Controller (RIC), such as an RIC(e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO) system, such as an SMO system, or any combination thereof. An RUmay also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). One or more components of the network entitiesin a disaggregated RAN architecture may be co-located, or one or more components of the network entitiesmay be located in distributed locations (e.g., separate physical locations). In some examples, one or more of the network entitiesof a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

160 165 170 160 165 170 160 165 160 165 160 160 165 170 165 170 160 165 170 165 170 165 170 160 165 165 170 160 165 170 160 165 170 160 160 165 162 165 170 168 162 168 105 The split of functionality between a CU, a DU, and an RUis flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CUand a DUsuch that the CUmay support one or more layers of the protocol stack and the DUmay support one or more different layers of the protocol stack. In some examples, the CUmay host upper protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), service data adaptation protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU(e.g., one or more CUs) may be connected to a DU(e.g., one or more DUs) or an RU(e.g., one or more RUs), or some combination thereof, and the DUs, RUs, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DUand an RUsuch that the DUmay support one or more layers of the protocol stack and the RUmay support one or more different layers of the protocol stack. The DUmay support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU). In some cases, a functional split between a CUand a DUor between a DUand an RUmay be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU). A CUmay be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CUmay be connected to a DUvia a midhaul communication link(e.g., F1, F1-c, F1-u), and a DUmay be connected to an RUvia a fronthaul communication link(e.g., open fronthaul (FH) interface). In some examples, a midhaul communication linkor a fronthaul communication linkmay be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities) that are in communication via such communication links.

In some cases, in an IAB network, one or more of the network entities(e.g., network entitiesor IAB node(s)) may be partially controlled by each other. The IAB node(s)may be referred to as a donor entity or an IAB donor. A DUor an RUmay be partially controlled by a CUassociated with a network entityor base station(such as a donor network entity or a donor base station). The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node(s)) via supported access and backhaul links (e.g., backhaul communication link(s)). IAB node(s)may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEsor may share the same antennas (e.g., of an RU) of IAB node(s)used for access via the DUof the IAB node(s)(e.g., referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB node(s)may include one or more DUs (e.g., DUs) that support communication links with additional entities (e.g., IAB node(s), UEs) within the relay chain or configuration of the access network (e.g., downstream). In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node(s)or components of the IAB node(s)) may be configured to operate according to the techniques described herein.

104 115 130 130 130 160 165 170 160 130 104 160 130 160 For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor), IAB node(s), and one or more UEs. The IAB donor may facilitate connection between the core networkand the AN (e.g., via a wired or wireless connection to the core network). That is, an IAB donor may refer to a RAN node with a wired or wireless connection to the core network. The IAB donor may include one or more of a CU, a DU, and an RU, in which case the CUmay communicate with the core networkvia an interface (e.g., a backhaul link). The IAB donor and IAB node(s)may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol). Additionally, or alternatively, the CUmay communicate with the core networkvia an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs (e.g., including a CUassociated with an alternative IAB donor) via an Xn-C interface, which may be an example of another portion of a backhaul link.

104 115 165 104 104 104 104 104 104 104 104 165 115 IAB node(s)may refer to RAN nodes that provide IAB functionality (e.g., access for UEs, wireless self-backhauling capabilities). A DUmay act as a distributed scheduling node towards child nodes associated with the IAB node(s), and the IAB-MT may act as a scheduled node towards parent nodes associated with IAB node(s). That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through other IAB node(s)). Additionally, or alternatively, IAB node(s)may also be referred to as parent nodes or child nodes to other IAB node(s), depending on the relay chain or configuration of the AN. The IAB-MT entity of IAB node(s)may provide a Uu interface for a child IAB node (e.g., the IAB node(s)) to receive signaling from a parent IAB node (e.g., the IAB node(s)), and a DU interface (e.g., a DU) may provide a Uu interface for a parent IAB node to signal to a child IAB node or UE.

104 160 120 130 104 165 115 104 115 160 104 104 115 165 104 104 104 165 104 For example, IAB node(s)may be referred to as parent nodes that support communications for child IAB nodes, or may be referred to as child IAB nodes associated with IAB donors, or both. An IAB donor may include a CUwith a wired or wireless connection (e.g., backhaul communication link(s)) to the core networkand may act as a parent node to IAB node(s). For example, the DUof an IAB donor may relay transmissions to UEsthrough IAB node(s), or may directly signal transmissions to a UE, or both. The CUof the IAB donor may signal communication link establishment via an F1 interface to IAB node(s), and the IAB node(s)may schedule transmissions (e.g., transmissions to the UEsrelayed from the IAB donor) through one or more DUs (e.g., DUs). That is, data may be relayed to and from IAB node(s)via signaling via an NR Uu interface to MT of IAB node(s)(e.g., other IAB node(s)). Communications with IAB node(s)may be scheduled by a DUof the IAB donor or of IAB node(s).

115 105 140 165 160 170 175 180 In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support downlink control channel monitoring occasion configuration for on-demand system information as described herein. For example, some operations described as being performed by a UEor a network entity(e.g., a base station) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU, a CU, an RU, an RIC, an SMO system).

115 115 115 A UEmay include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UEmay also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UEmay include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.

115 115 105 1 FIG. The UEsdescribed herein may be able to communicate with various types of devices, such as UEsthat may sometimes operate as relays, as well as the network entitiesand the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in.

115 105 125 125 125 100 115 115 105 105 105 105 140 160 165 170 105 The UEsand the network entitiesmay wirelessly communicate with one another via the communication link(s)(e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link(s). For example, a carrier used for the communication link(s)may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications systemmay support communication with a UEusing carrier aggregation or multi-carrier operation. A UEmay be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entityand other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network entity, may refer to any portion of a network entity(e.g., a base station, a CU, a DU, a RU) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities).

115 115 In some examples, such as in a carrier aggregation configuration, a carrier may have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN)) and may be identified according to a channel raster for discovery by the UEs. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEsvia the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different RAT).

125 100 105 115 115 105 The communication link(s)of the wireless communications systemmay include downlink transmissions (e.g., forward link transmissions) from a network entityto a UE, uplink transmissions (e.g., return link transmissions) from a UEto a network entity, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode).

100 100 105 115 100 105 115 115 A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communications system(e.g., the network entities, the UEs, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications systemmay include network entitiesor UEsthat support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UEmay be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

115 Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam), and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE.

115 115 One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UEmay be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UEmay be restricted to one or more active BWPs.

105 115 s max f max f The time intervals for the network entitiesor the UEsmay be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T=1/(Δf·N) seconds, for which Δfmay represent a supported subcarrier spacing, and Nmay represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

100 f Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems, such as the wireless communications system, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N) sampling periods.

The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

100 100 A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications systemand may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications systemmay be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

115 115 115 115 Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs. For example, one or more of the UEsmay monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs(e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE(e.g., a specific UE).

105 105 110 110 105 110 A network entitymay provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity(e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)). In some examples, a cell also may refer to a coverage areaor a portion of a coverage area(e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas, among other examples.

115 105 140 115 115 115 115 105 A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEswith service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a network entityoperating with lower power (e.g., a base stationoperating with lower power) relative to a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEswith service subscriptions with the network provider or may provide restricted access to the UEshaving an association with the small cell (e.g., the UEsin a closed subscriber group (CSG), the UEsassociated with users in a home or office). A network entitymay support one or more cells and may also support communications via the one or more cells using one or multiple component carriers.

In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access for different types of devices.

105 140 170 110 110 110 105 110 105 100 105 110 In some examples, a network entity(e.g., a base station, an RU) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area. In some examples, coverage areas(e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas(e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity). In some other examples, overlapping coverage areas, such as a coverage area, associated with different technologies may be supported by different network entities (e.g., the network entities). The wireless communications systemmay include, for example, a heterogeneous network in which different types of the network entitiessupport communications for coverage areas(e.g., different coverage areas) using the same or different RATs.

115 105 140 115 Some UEs, such as MTC or IoT devices, may be relatively low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity(e.g., a base station) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEsmay be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

115 115 115 Some UEsmay be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently). In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEsmay include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEsmay be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs)) within a carrier, within a guard-band of a carrier, or outside of a carrier.

100 100 115 The wireless communications systemmay be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications systemmay be configured to support ultra-reliable low-latency communications (URLLC). The UEsmay be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

115 115 135 115 110 105 140 170 105 115 110 105 105 115 115 115 105 115 105 In some examples, a UEmay be configured to support communicating directly with other UEs (e.g., one or more of the UEs) via a device-to-device (D2D) communication link, such as a D2D communication link(e.g., in accordance with a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEsof a group that are performing D2D communications may be within the coverage areaof a network entity(e.g., a base station, an RU), which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity. In some examples, one or more UEsof such a group may be outside the coverage areaof a network entityor may be otherwise unable to or not configured to receive transmissions from a network entity. In some examples, groups of the UEscommunicating via D2D communications may support a one-to-many (1:M) system in which each UEtransmits to one or more of the UEsin the group. In some examples, a network entitymay facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEswithout an involvement of a network entity.

130 130 115 105 140 130 150 150 The core networkmay provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core networkmay be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEsserved by the network entities(e.g., base stations) associated with the core network. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP servicesfor one or more network operators. The IP servicesmay include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service.

100 115 The wireless communications systemmay operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEslocated indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

100 100 115 105 140 170 The wireless communications systemmay also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz, also known as the centimeter band, or using an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as the millimeter band. In some examples, the wireless communications systemmay support millimeter wave (mmW) communications between the UEsand the network entities(e.g., base stations, RUs), and EHF antennas of the respective devices may be smaller and more closely spaced than UHF antennas. In some examples, such techniques may facilitate using antenna arrays within a device. The propagation of EHF transmissions, however, may be subject to even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions may differ by country or regulating body.

100 100 105 115 2 The wireless communications systemmay utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications systemmay employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entitiesand the UEsmay employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, PP transmissions, or D2D transmissions, among other examples.

105 140 170 115 105 115 105 105 105 115 115 A network entity(e.g., a base station, an RU) or a UEmay be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entityor a UEmay be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entitymay be located at diverse geographic locations. A network entitymay include an antenna array with a set of rows and columns of antenna ports that the network entitymay use to support beamforming of communications with a UE. Likewise, a UEmay include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.

105 115 The network entitiesor the UEsmay use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), for which multiple spatial layers are transmitted to multiple devices.

105 115 Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity, a UE) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).

105 115 105 140 170 115 105 105 105 115 105 A network entityor a UEmay use beam sweeping techniques as part of beamforming operations. For example, a network entity(e.g., a base station, an RU) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entitymultiple times along different directions. For example, the network entitymay transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity, or by a receiving device, such as a UE) a beam direction for later transmission or reception by the network entity.

105 115 105 115 115 105 105 115 Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network entityor a UE) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entityor UE). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UEmay receive one or more of the signals transmitted by the network entityalong different directions and may report to the network entityan indication of the signal that the UEreceived with a highest signal quality or an otherwise acceptable signal quality.

105 115 105 115 115 105 115 105 140 170 115 115 In some examples, transmissions by a device (e.g., by a network entityor a UE) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entityto a UE). The UEmay report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entitymay transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or unprecoded. The UEmay provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted along one or more directions by a network entity(e.g., a base station, an RU), a UEmay employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device).

115 105 A receiving device (e.g., a UE) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity), such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

100 115 105 130 The wireless communications systemmay be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UEand a network entityor a core networksupporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.

115 105 125 135 The UEsand the network entitiesmay support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link(s), a D2D communication link). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

100 105 115 105 105 115 The wireless communications systemmay support techniques for communication of system information. For example, a network entitymay transmit SIBs, such as a SIB1, to a UE. Some SIBs may be associated with a periodicity. For example, SIB1 may have a periodicity of 160 milliseconds before contents of the SIB1 may be updated or changed. Within the SIB1 periodicity (e.g., 160 milliseconds), the network entitymay transmit a SIB1 multiple times according to a SIB1 transmission repetition periodicity. For example, the network entitymay transmit a SIB1 eight times if the SIB1 periodicity is 160 milliseconds and the SIB1 transmission repetition periodicity is 20 milliseconds. A UEwith low SNR may receive and combine multiple repeated SIB1 to decode the SIB1. In some cases, SIB1 may be beam swept over all transmitted SSBs in consecutive slots within a SIB1 transmission repetition periodicity.

100 100 105 115 115 115 115 115 The wireless communications systemmay implement techniques for network energy savings. For example, the wireless communications systemmay support on-demand system information, including on-demand SIB1. For example, a network entitymay transmit an uplink WUS configuration to a UEindicating parameters for the UEto transmit an uplink WUS to a serving cell, such as a network energy savings serving cell. The UEmay receive a SSB of an SSB burst and transmit a WUS to the serving cell during a random access occasion. The WUS may, in some examples, request on-demand system information from the serving cell, such as requesting an on-demand SIB1. In some cases, the WUS may include aspects of a random access preamble. The serving cell may transmit an RAR message to the UEin response to the WUS, and the RAR message may indicate that the UEis to begin monitoring for the on-demand SIB1.

115 115 115 In some cases, the UEmay transmit the WUS to request on-demand other system information (OSI). The RAR message may trigger the UEto start monitoring for the on-demand OSI in one or more system information windows. A time offset to the system information window to receive the on-demand OSI may be based on information in SIB1 or statically configured. A duration of the system information window to receive the on-demand OSI may be configured by SIB1. Upon receipt of the RAR message, the UEmay monitor one or more system information windows until successful acquisition within a current modification period of the system information.

115 When requesting on-demand SIB1, an RAR message may trigger the UEto monitor for PDCCH signaling in a PDCCH window. A start of the PDCCH window may be offset from a reference time point. The term “PDCCH window” may be referred to as or include aspects of a PDCCH monitoring window (e.g., from a UE perspective) or a PDCCH transmission window (e.g., from a network perspective).

105 In some examples, the reference time point may correspond to a reception time of the RAR message. In this example, a same offset may be used for different RAR messages. For example, a first RAR message transmitted early in the RAR window may have a same length offset as a second RAR message transmitted later in the RAR window, such that a first PDCCH monitoring window corresponding to the first RAR message begins earlier than a second PDCCH monitoring window corresponding to the second RAR message. In this case, the network entitymay transmit the one-demand SIB1 in a larger PDCCH monitoring window than the UE-side PDCCH monitoring windows, as the network-side PDCCH monitoring window may have a duration equal to a union of all UE-side PDCCH monitoring windows. This example may provide lower latency, but uses higher network energy consumption.

115 In some examples, the reference time point may correspond to a transmission time of the uplink WUS. The UEmay wait for the RAR message to determine whether to retransmit the uplink WUS, as an initial transmission of an uplink WUS may not be successfully received. Therefore, using the transmission time of the uplink WUS may, in some cases, be less reliable than the PDCCH monitoring window being based on a timing related to the RAR message.

In some examples, the reference time point may be based on the RAR window, for example instead of a receipt of a specific RAR within the RAR window. For example, the reference time point may be based on an end of the RAR window. In this example, both the network-side and the UE-side PDCCH monitoring windows may be aligned.

100 The wireless communications system, and wireless communications systems described herein, support additional techniques to provide for aligning UE-side and network-side PDCCH windows by configuring a start time and a duration of a PDCCH window for on-demand system information, such as on-demand SIB1. In some examples, a starting time and a duration of the PDCCH window may be indicated in the RAR message that is response to the uplink WUS. In some examples, the starting time and the duration of the PDCCH window may be indicated in the uplink WUS configuration.

In some examples, the PDCCH window may start right after an offset from a reference time. The PDCCH window may or may not align with a Type-0 PDCCH occasion associated with the uplink WUS occasion. The PDCCH window duration may be based on a target quantity of on-demand SIB1 transmissions and a maximum time offset to the earliest PDCCH occasion.

115 115 115 In some examples, the PDCCH window may align with a corresponding Type-0 PDCCH occasion. A UEmay receive a first SSB and transmit an uplink WUS to a serving cell in a random access occasion corresponding to the first SSB. The serving cell may transmit an RAR message to the UEin response to the uplink WUS to configure the UEto monitor for an on-demand SIB1 in a PDCCH window after a time offset from a reference time point. A beginning of the PDCCH window may align with an earliest Type-0 PDCCH occasion corresponding to the first SSB after the time offset. A duration of the PDCCH window may be based on a target quantity of SIB1 transmissions.

The starting time and/or duration of the PDCCH window for the on-demand system information (e.g., on-demand SIB1) may be indicated semi-statically via the uplink WUS configuration, dynamically by the RAR message, statically configured, or any combination thereof. The starting time may be indicated based on an offset from a reference time point. For example, the PDCCH monitoring window may begin right after the offset from the reference time point, or a starting boundary of the PDCCH monitoring window may align with a corresponding PDCCH occasion, as described above. In some examples, the reference time point may be referred to as a reference time.

100 115 115 115 115 The wireless communications systemmay support techniques for a UEto receive multiple on-demand SIB1s within a PDCCH window. For example, a duration of the PDCCH window may be configured to be large enough for the UEto receive a target quantity of repeated SIB1s based on an SNR of the UE. For example, the PDCCH window duration may be configured to be equal to the target quantity of repeated SIB1s times the SIB1 transmission repetition periodicity. If, for example, the UEcan decode the SIB1 by combining four repetitions of the SIB1, and the SIB1 transmission repetition periodicity is 20 milliseconds long, the PDCCH window may be configured to be at least 80 milliseconds long.

100 105 115 105 115 105 115 105 115 The wireless communications systemmay support techniques for slot aggregation of on-demand SIB1. Physical downlink shared channel (PDSCH) slot aggregation may be used to transmit repeated SIB1s in consecutive slots to reduce SIB1 acquisition latency and save power consumption for both a network entityand a UE. A slot aggregation parameter may be semi-statically indicated via an uplink WUS configuration or dynamically indicated via an RAR message, or both. If a network entityreceives multiple WUS from multiple UEs, the network entitymay dynamically adjust timing information for PDCCH windows of the UEsto avoid resource conflicts. For example, the network entitymay adjust a PDCCH window start time or duration or a slot aggregation parameter for one or more of the UEs.

2 FIG. 200 shows an example of a wireless communications systemthat supports downlink control channel monitoring occasion configuration for on-demand system information in accordance with one or more aspects of the present disclosure.

200 100 200 115 105 115 105 a a The wireless communications systemmay include aspects of a wireless communications system. For example, the wireless communications systemincludes a UE-and a network entity-, which may be respective examples of a UEand a network entitydescribed herein.

The network entity-may transmit a control signal indicating an uplink WUS configurationto the UE-. The UE-may transmit an uplink WUSto the network entity-. The uplink WUSmay trigger or request an on-demand SIB1. In some examples, the UE-may transmit the uplink WUS via a random access occasion. The network entity-may transmit an RAR messagein response to the uplink WUS, which may configure the UE-to monitor for the on-demand SIB1. The network entity-may transmit the on-demand SIB1to the UE-during a PDCCH window.

The UE-may monitor for an RAR messagein an RAR window-In this case, the UE-may not receive an RAR messagein the RAR window-At a second random access occasion, the UE-may transmit a WUS-and monitor an RAR window-for an RAR message. In this case, the UE-may receive an RAR messageduring the RAR window-

215 225 115 220 235 215 115 200 215 115 200 215 b a The RAR messagereceived during the RAR window-may configure the UE-to monitor for the on-demand SIB1during a PDCCH windowthat is offset from a reference time point. In some examples, the reference time point may be indicated via the uplink WUS configuration or the RAR message. In some cases, the reference time point may be statically configured (e.g., for the UEor the wireless communications system) or specified in a technical specification. In some examples, the time offset may be indicated via the uplink WUS configuration or the RAR message. In some cases, the time offset may be statically configured (e.g., for the UEor the wireless communications system) or standardized. For example, the time offset may be statically configured based on a PDSCH processing latency for RAR messages.

In some cases, a same time offset may be used for different RAR messages, where a time offset-and a time offset-may be a same duration or length of time. For example, a first RAR message-transmitted early in the RAR window-may have a same length offset as a second RAR message-transmitted later in the RAR window-, such that a first UE-side PDCCH window-corresponding to the first RAR message-begins earlier than a second UE-side PDCCH window-corresponding to the second RAR message-. In this case, the network entity-may transmit on-demand SIB1s in a larger, network-side PDCCH window, as the network-side PDCCH windowmay have a duration equal to a union of all UE-side PDCCH windows. This example may provide lower latency, but uses higher network energy consumption.

115 115 215 210 210 235 215 225 a a a In some examples, the reference time point may correspond to a transmission time of the uplink WUS. The UE-may wait for the RAR message to determine whether to retransmit the uplink WUS, as an initial transmission of an uplink WUS may not be successfully received. For example, the UE-did not receive an RAR messagein response to the uplink WUS-. Therefore, using the transmission time of the uplink WUSmay, in some cases, be less reliable than configuring the PDCCH windowto be based on timing information of the RAR messageor the RAR window.

225 225 225 In some examples, the reference time point may be based on the RAR window. For example, the reference time point may be based on an end of the RAR windowinstead of a receipt of a specific RAR message within the RAR window. In this example, both the network-side and the UE-side PDCCH monitoring windows may be aligned.

200 The wireless communications systemmay support techniques to align UE-side and network-side PDCCH windows by configuring a start time and a duration of a PDCCH window for on-demand system information, such as on-demand SIB1. In some examples, a starting time or a duration of the PDCCH window may be indicated in the RAR message that is response to the uplink WUS. Additionally, or alternatively, the starting time or the duration of the PDCCH window may be indicated in the uplink WUS configuration.

115 215 225 205 215 215 230 235 230 215 235 235 115 235 220 230 a a b a a a a For example, the UE-may receive the first RAR message-during the RAR window-. A reference time point may be indicated by the uplink WUS configurationor the first RAR message-, or the reference time point may be statically configured (e.g., specified in a technical specification). The uplink WUS configuration or the first RAR message-may indicate a time offsetfrom the reference time point to a PDCCH window, or the time offsetmay be statically configured (e.g., specified in a technical specification). The uplink WUS configuration or the first RAR message-may indicate a duration of the PDCCH windowfrom the reference time point, or the duration of the PDCCH windowmay be statically configured (e.g., specified in a technical specification). The UE-may monitor the PDCCH windowfor the on-demand SIB1after the time offsetfrom the reference point.

235 230 235 230 235 235 b b In some examples, the PDCCH windowmay start right after the time offsetfrom a reference time. For example, the UE-side PDCCH window-is shown to begin right after the time offsets-from the reference time point. The PDCCH windowmay or may not align with a Type-0 PDCCH occasion associated with the uplink WUS occasion. A duration of the PDCCH windowmay be based on a target quantity of on-demand SIB1 transmissions and a maximum time offset to the earliest associated Type-0 PDCCH occasion.

235 115 210 215 115 210 115 230 230 235 a b a b a In some examples, a beginning of the PDCCH windowmay align with a corresponding Type-0 PDCCH occasion. A UE-may receive a first SSB and transmit the uplink WUS-to a serving cell in a random access occasion corresponding to the first SSB. The serving cell may transmit an RAR messageto the UE-in response to the uplink WUS-to configure the UE-to monitor for an on-demand SIB1 in a PDCCH window after a time offsetfrom a reference time point. A beginning of the PDCCH window may align with an earliest Type-0 PDCCH occasion corresponding to the first SSB after the time offset. A duration of the PDCCH windowmay be based on a target quantity of SIB1 transmissions.

The starting time and/or duration of the PDCCH window for the on-demand system information (e.g., on-demand SIB1) may be indicated semi-statically via the uplink WUS configuration, dynamically by the RAR message, statically configured, or any combination thereof. The starting time may be indicated based on an offset from a reference time point. For example, the PDCCH monitoring window may begin right after the offset from the reference time point, or a starting boundary of the PDCCH monitoring window may align with a corresponding PDCCH occasion, as described herein.

205 205 In some examples, the starting time may align with a slot or symbol boundary. The slot or symbol may be defined based on a downlink default SCS, specified via a MIB, or based on an SCS indicated via the uplink WUS configuration. In some examples, the duration of the PDCCH window may be defined as a quantity of milliseconds, a quantity of slots, or a quantity of SSB periods. A slot of the quantity of slots may be based on the downlink default SCS (e.g., specified via the MIB) or based on an SCS indicated via the uplink WUS configuration.

215 215 225 215 215 215 205 205 215 215 225 The reference point may be based on a received RAR message, such as based on a time of receipt for the RAR message, or based on an RAR windowwith the received RAR message. In some examples, the reference time point may be statically configured or standardized. In some examples, different types of reference time points may be defined based on a message type indicating the starting time. For example, the reference time point is based on the received RAR messageif the starting time is dynamically indicated by the received RAR message. In some other examples, the reference time point may be based on the RAR window if the starting time is semi-statically configured by the uplink WUS configuration. In some examples, the reference time point may be indicated by the uplink WUS configurationor the RAR message, or both, to select between using the received RAR messageand the RAR windowas the reference time point.

215 235 235 215 215 230 215 205 For example, an RAR messagemay indicate one or more parameters including a starting time of a PDCCH windowor a duration of the PDCCH window. In some examples, a parameter indicated by the RAR messagemay be an actual value of the parameter. For example, the RAR messagemay indicate an explicit value for a starting time of the PDCCH window, a delay between a time offsetand a start of the PDCCH window, or both. Additionally, or alternatively, the RAR messagemay indicate an explicit value for a duration of the PDCCH window, such as a quantity of slots, symbols, or SSB periods. The value indicated by the RAR message may override or replace a value configured by the uplink WUS configurationor a statically configured or standardized value.

215 205 215 In some examples, the RAR messagemay indicate a parameter by indicated an index to a list of values. For example, the uplink WUS configurationmay configure a list of values for the parameter, and the RAR messagemay select one value from the list of values for the parameter. Additionally, or alternatively, the list of values for the parameter for may be statically configured or specified in a technical specification.

215 215 205 In some examples, the RAR messagemay indicate a parameter by indicating a delta value or a differential from another parameter value. For example, the RAR messagemay indicate a delta value to apply and adjust a parameter value configured by the uplink WUS configurationor a statically configured, or standardized, parameter value.

215 235 205 235 215 235 205 215 In some examples, parameters may be indicated by the RAR message, the uplink WUS configuration, or a static configuration, or any combination thereof. For example, the reference time point may be statically configured (e.g., specified in a technical specification), the duration of the PDCCH windowmay be semi-statically configured by the uplink WUS configuration, and the starting time of the PDCCH windowmay be indicated by the RAR message. Additionally, or alternatively, the reference time point may be statically configured, the starting time and duration of the PDCCH windowmay be semi-statically configured by the uplink WUS configuration, and the starting time and duration of the PDCCH window may be optionally indicated or updated by the RAR message.

215 215 215 225 215 215 105 235 115 215 115 215 105 230 215 115 215 a b b In some examples, different RAR messagewithin a same RAR window may carry the same or different parameters. For example, the first RAR message-and the second RAR message-may each be transmitted within the RAR window-, and these RAR messagemay indicate the same or different parameters. For example, if the reference time point is based on the received RAR message, the network entitymay indicate different starting offsets in different RAR messages such that the starting time of the PDCCH windowsfor the UEsare aligned (e.g., regardless of which RAR messageis received by which UE). In some other examples, if the reference time point is based on the received RAR message, the network entitymay indicate the same time offsetin different RAR messagessuch that each UEcan acquire the on-demand SIB1 as soon as possible after the received RAR message.

A network entitymay configure a UEwith an uplink WUS configuration, and the UEmay transmit an uplink WUS to request on-demand system information, such as an on-demand SIB1. The network entitymay periodically transmit an SSB burst, and the UEmay receive an SSB.

For example, the UEmay monitor a PDCCH occasion, such as a Type-0 PDCCH occasion, that corresponds to the received SSBfor a downlink control information grant that schedules a PDSCH. The network entitymay transmit the on-demand SIB1 via the PDSCH.

Timing information, such as a starting time of a PDCCH window, duration of the PDCCH window, a reference time point, and a timing offset from the reference time point, or any combination thereof, may be indicated via the uplink WUS configuration or the RAR message, or both. Additionally, or alternatively, some parameters of the timing information may be statically configured or specified in a technical specification.

4 FIG. 400 shows an example of a slot aggregation configurationthat supports downlink control channel monitoring occasion configuration for on-demand system information in accordance with one or more aspects of the present disclosure.

105 115 105 115 105 115 105 115 A wireless communications system may support techniques for slot aggregation of on-demand SIB1. PDSCH slot aggregation may be used to transmit repeated SIB1s in consecutive slots to reduce SIB1 acquisition latency and save power consumption for both a network entityand a UE. A slot aggregation parameter may be semi-statically indicated via an uplink WUS configuration or dynamically indicated via an RAR message, or both. If a network entityreceives multiple WUS from multiple UEs, the network entitymay dynamically adjust timing information for PDCCH windows of the UEsto avoid resource conflicts. For example, the network entitymay adjust a PDCCH window start time or duration or a slot aggregation parameter for one or more of the UEs.

115 405 410 415 415 405 415 115 405 115 410 105 415 405 430 405 105 420 410 a a a a b b b b b For example, a UEmay receive a first SSB-and transmit an uplink WUSduring a random access occasion-. The random access occasion-may be associated with the first SSB-, while some other random access occasionsare associated with other SSBs. For example, if the UEreceived a second SSB-, the UEmay transmit the uplink WUSto a network entityduring a random access occasion-associated with the second SSB-and monitor for SIB1 signaling based on a PDCCH occasion-associated with the second SSB-. The network entitymay transmit an RAR messagein response to the uplink WUS.

420 420 425 425 The RAR messageor an uplink WUS configuration, or both, may indicate timing information or timing parameters as described herein. For example, the RAR messageor the uplink WUS configuration, or both, may indicate a reference time point, a time offset, a start duration of a PDCCH window, a duration of the PDCCH window, or any combination thereof.

105 105 420 105 115 115 105 The network entitymay use slot aggregation to transmit repeated SIB1s in consecutive slots. For example, the network entitymay indicate a slot aggregation parameter via the RAR messageor the uplink WUS configuration, or both. In some examples, the slot aggregation parameter may be statically configured or specified in a technical specification. For example, the network entitymay indicate a slot aggregation parameter K to the UE, where K is set to 2, 4, or 8, or another quantity. In some cases, if the UEis not configured with a slot aggregation parameter, the network entitymay not utilize slot aggregation.

115 430 425 115 430 405 115 435 115 435 435 435 a a a b The UEmay begin monitoring a PDCCH search space during a PDCCH occasionin the PDCCH window. For example, the UEmay monitor for PDCCH signaling during a PDCCH occasion-, which is associated with the received SSB (e.g., the first SSB-). The UEmay receive a grant that schedules a PDSCH slot aggregation for transmission of a SIB1over consecutive slots based on the slot aggregation parameter. For example, if the slot aggregation parameter is set to K=2, the UEmay receive two SIB1s(e.g., a SIB1-and a SIB1-) in two consecutive slots.

425 115 105 115 435 115 440 When using slot aggregation, a duration of the PDCCH windowmay be based on a target quantity of SIB1s. For example, the UEmay be at a cell edge of the network entity, and the UEmay require combining N repetitions of a SIB1to decode the SIB1. In some examples, the repetition factor, K, may be set to be larger than or equal to N. The PDCCH window duration may be set to a quantity of repeated SIB1s required for the UEtimes a SIB1 transmission repetition periodicity.

105 105 435 In some systems, a network entitymay transmit SIB1s mapped to a same SSB that correspond to a requesting uplink WUS. Using slot aggregation, the network entitymay transmit repeated SIB1sin consecutive slots to reduce SIB1 acquisition latency and save power consumption.

115 115 115 115 In some cases, the wireless communications system may support additional, or alternative, techniques for a UEto receive multiple on-demand SIB1s within a PDCCH window without using slot aggregation. For example, a duration of the PDCCH window may be configured to be large enough for the UEto receive a target quantity of repeated SIB1s based on an SNR of the UE. For example, the PDCCH window duration may be configured to be equal to the target quantity of repeated SIB1s times the SIB1 transmission repetition periodicity. If, for example, the UEcan decode the SIB1 by combining four repetitions of the SIB1, and the SIB1 transmission repetition periodicity is 20 milliseconds long, the PDCCH window may be configured to be at least 80 milliseconds long.

105 115 105 115 105 115 105 115 A wireless communications system may support techniques for slot aggregation of on-demand SIB1. PDSCH slot aggregation may be used to transmit repeated SIB1s in consecutive slots to reduce SIB1 acquisition latency and save power consumption for both a network entityand a UE. A slot aggregation parameter may be semi-statically indicated via an uplink WUS configuration or dynamically indicated via an RAR message, or both. If a network entityreceives multiple WUS from multiple UEs, the network entitymay dynamically adjust timing information for PDCCH windows of the UEsto avoid resource conflicts. For example, the network entitymay adjust a PDCCH window start time or duration or a slot aggregation parameter for one or more of the UEs.

Thus, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components,” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.”

The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure), ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.

In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.

The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples.” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.

The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
